(1) The maximum total current, I_OH(max) and I_OL(max), for all outputs combined, should not exceed ±12 mA to hold the maximum voltage drop
specified.
(2) The maximum total current, I_OH(max) and I_OL(max), for all outputs combined, should not exceed ±48 mA to hold the maximum voltage drop
specified.

(1) A resistive divider with 2 times 0.5 kΩ between V_CC and V_SS is used as load. The output is connected to the center tap of the divider.
(2) The output voltage reaches at least 10% and 90% V_CC at the specified toggle frequency.
